HARNESS-MACHINE.

SPECIFICATION forming part of Letters Patent No. 485,065, dated October25, 1892.

Application filed June 8, 1892. Serial No. 435,996. (No model.)

To all whom it may concern:

Be it known that we, GEORGE STEINBACH and HENRY SHAFER, of Bethel, inthe county of Shelby and State of Missouri, have invented certain newand useful Improvements in Har- Tress-Machines; and we do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanyingdrawings, which form part of this specification.

Our invention relates to an improvement in harness-machines; and itconsists in the novel features of construction and in the combinationand arrangement of parts, which will be fully described hereinafter, andmore particularly referred to in the claims.

The object of our invention is to provide an improved machine forpunching straps and other portions of harness previous to stitching thesame, whereby the work is accomplished with rapidity and accuracy.

Referring to the accompanying drawings, Figure 1 is a perspective viewof our improved machine. Fig. 2 is a side elevation of the same. Fig. 3is a detached view of the vertically-adjustable gage-table. Fig. 4: is adetached view of the feed-roll.

A represents the front and B the rear portion of the frame, both beingformed of a single casting. J ournaled in suitable bearings in the frontportion A is the vertical feed-roll C, carrying the toothed wheel 0 nearits upper end for engaging the surface of the leather which is beingoperated upon. Upon the lower end of the said roll is secured theperipherally-serrated Wheel D, which projects at one side through a slotin the downwardlyextending flange B for the purpose presently to beexplained.

E represents the feed-table, which is recessed between its ends, asshown, so as to fit over the roll O. Projecting from the front side ofthis table is the clamp F, which engages the side of the base A, movingvertically thereon, and by means of the set-screw of the said clamp thetable maybe secured at any desired distance from the horizontallymovingpunch, and by this means the stitching may be placed at the properdistance inward from the edge of the leather. The side of the baseportion A, and thus the table is always square with the feed-roll.

G represents a horizontal extension projecting from the side of theportion B, and journaled to the outer end of the said extension is theframe H, which projects inward over the feed-roll O. J ournaled in theouter end of the said frame adjacent the said roll is the roller 1. Theouter end of this frame and the roller I, carried thereby, are heldnormally inward against the recessed side of the table E by the coiledspring J, which encircles the pivotal point of the said frame H, one ofthe springs bearing, as shown, against the table and the other adjustably secured to the side of the extension G by the rack G. By meansof the latter the tension of the spring on the frame Il may beregulated. The object of this spring-actuated frame is to keep theleather pressed tightly against the feed-roller and in a positiveposition all the time in relation thereto, so that the work may beaccurately done.

Projecting laterally from the outer end of the portion B is the long hubK, and mounted thereon adjacent the said portion is the operating-leverL, which is held normally projecting upward at its lower end by thespring K, which is coiled around the hub K. Projecting upward from therear end of this lever is the arm M, and pivoted thereto is theforwardly-projecting link N, which is connected at its outer end to theclamp O, in which is secured the horizontally-moving rod or bar P,carrying the punch P at its outer on d. This bar P is held in itshorizontal position by the projecting guides Q, extending from the edgeof the portion B of the frame.

R represents a rod, which is adjustable 1ongitudinally in theprojections Q, and to the forward end of this rod is secured the foot B,through which the punch is projected in piercing the leather. This footserves as a guide for the punch and leather, and also holds the latterwhen the former is being withdrawn therefrom in its outward movement.

By means of the clamp O the hold on the rod P may be adjusted to anydesired point and the length of the stroke of the punch and against theclamp O and stop P, respectively, at their opposite ends." The twolatter points are also by this construction prevented from coming inviolent contact with thesaid guides in the forward movementof thepunch-carrying rod.

Extending downward from the rearwardly extending portion B are theperforated guides T T, and adapted to move horizontally therethrough isthe rod U. Coiled around the said rod and adapted to rest on the guide Tis the spring U, which bears at its opposite end against the screw-nutV, which is adjustable on the upper screw-threaded end of the rod U. Theupper end of the said rod projects through the upper guide T, and itwill be seen that the distance which it projects will be regulated bythe adjustment of the nut V. Projecting downward from the lever L is thearm W, having the flattened projection W on its lower end,which normallyrests on the guide T, being held in contact therewith by the tension ofthe spring K. When the lever L is pushed rearward, the said arm WV willbe raised and the rod U, by means of the spring U, will be forced upwardthrough the said guide to the extent of the length of the end of the rodprojecting from the nut V. Thus, itwill be seen, by adjusting the saidnut longitudinally the length of the stroke of the rod U may beregulated. One end of the rod U is formed into a dog, which engages theserrated edge of the wheel D on the lower end of the feed-roll O, androtary movement of this roll is accomplished by the longitudinalmovement of the said rod. The said dog is held in engagement with thewheel D by the flat spring X, which is secured at its outer end to theside of the rod U. The spring and rod at this point extend through theloop Y, projecting from the portion B of the frame. The pressure of thespring is against this loop, thus holding the dog pushed inward and inengagement with the wheel D. A complete automatic feed mechanism is thusprovided, which moves the work the desired distance at the completion ofeach forward stroke of the punch, placing it in position to receive thenext perforation.

It'will'be readily understood that the 'dis tance between the stitchesin the leather may beregulated by adjusting the nut V so as to give therod U a long or short movement.

The treadle being operated by the foot, both hands of the operator arefree to sew,

and thus the work may be very rapidly accomplished.

Having thus described our invention, we claim 1. The combination, with aframe and a lever journaled thereto, of a punch-carrying bar mounted inthe frame, an arm projecting from said lever, a link secured to the arm,and an adjustable connection between the link and thesaid bar,substantially as shown and described.

2. The combination, with a' frame and an elongated hub projectingtherefrom, of alever mounted on the said hub, a spring coiled around thehub and secured at one end to the lever, a punch carrying bar in theframe, and

3. The combination, with a frame, a feedroll, and a punch carrying bar,of a lever journaled to the frame, oppositely-extending arms projectinglaterally from the said lever,

a suitable connection between one of the said scribed.

5.
